摘要：
Modern engineering system is usually a multi-field coupling system with complex structure/mechanical system as the main body, which integrates thermal, electromagnetic, fluid and other subsystems. The dynamics modeling of these systems are complex and their numerical calculate are also difficult, which bring unprecedented challenges to the efficient and accurate evaluation and design optimization of the system dynamic characteristics. In this paper, the research progress of multi-field coupling dynamics simulation methods for complex engineering systems are reviewed in detail, including the basic strategies of multi-field coupling dynamics modeling and numerical solution, mesh deformation processing method, coupling data exchange technology, numerical calculation efficiency, etc. On this basis, for uncertain multi-field coupling engineering systems, their uncertainty analysis and reliability evaluation methods under single and hybrid uncertainties are discussed in detail. This review paper is expected to provide some useful references for related researchers. © 2023 Advances in Mechanics.
